MINE-CAR.

SPECIFICATION forming part of Letters Patent No. 770,498, dated September 20, 1904, Application filed December 18, 1903. Serial No. 185,613. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM E. HAMILTON, a citizen of the United States, residing in the city of Zanesville, county of Muskingum, and State of Ohio, have invented a new and useful Improvement in Mine-Cars, of which the following is a specification.

My invention relates to mining machinery, and has for its principal objects to provide a mine-car having a large capacity without being walled up by hand, to provide amine-car especially adapted for use with a loading-Inachine, to provide a mine-car with high sides and that yet may be filled within low minechambers, to provide a mine-car to cooperate with a loading-machine with which it is used for the purpose of preventing the tendency of the machine to slue around, to providea mine-car that will keep its proper position relative to the loading-machine while being filled, to provide novel means for coupling a mine-car and loading-machine together, and

other objects hereinafter more fully appear- 1ng.

My invention consists in the parts and in the combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, and wherein like symbols refer to like parts wherever they occur, Figure 1 is a plan view of my improved mine-car and a loading-machine in position to fill the car. Fig. 2 is an end view of my improved mine-car. Fig. 3 is a sectional view of the mine-car, showing the rear end of the final conveyer of the loading-machine projecting therein. Fig. 4 is a detail of a modification of the means on the loading-machine for coupling with the car.

On account of the low roofs prevailing in mine-chambers mine-cars are ordinarily made very low and shallow, so as to leave room to permit shoveling the material to be loaded into the car, and the rear end wall is especially low and lower than the side walls. The car being filled,it is then walled up on the sides with lumps and filled in behind by hand. This method of loading is a slow and expen- The loading-machine shown in the accom-- panying drawings is of the type shown in my ,copending application filed October 20, 1903, Serial No. 177,750, to which reference is made for a detailed description. Briefly described,

the loading-machine comprises a wheeled truck 1, having pivotally mounted thereon a gathering mechanism or initial conveyer 2 and a picking-table or final conveyer 3. The

rear end of the final conveyer rests upon a supporting-bar 4, which is provided with a series of holes 5. Pins 6 may be removably inserted in the holes, one upon each side of the final conveyer 3, to hold it in place. The

.rear end of the final conveyer is provided with laterally-extending ears 7 8, made of angle-iron, which cooperate with parts upon the mine-car to be hereinafter described.

The mine-car comprises a floor 9 and walls 10 11, which are secured together by iron straps 12, bolted thereto. provided in the rear end wall of the car. Iron straps 14 15 extend along the sides of the opening and down the rear end wall, serving to hold the parts together and to strengthen the wall. The lower side of the opening is substantially at theheight of the top of the rear end wall of the ordinary mine-car. In the construction shown projections above this point are arranged upon either side, and thus form the opening. For the purpose of anchoring the loading-machine standards occupying the position of the straps 14 15 will serve. It is preferable to build up the end wall on either side, however, as the capacity of the car is increased. Ears 16 17, having open bearings 18 19, are mounted upon each side of the opening, at the lower edge thereof.

An opening 13 is I A bearing-roller 20, provided with journals 21 22, engaging said bearings, rests in said cars. When projecting through the opening in the car. the rear end of the conveyer may rest upon the said roller, which will permit relative longitudinal movement of the load-' surfaces presented by the pyramidal arms.

The downwardly-extending arms are made heavy by enlargements 25 26, so as to hold the bell-cranks in position. These catches are engaged by the ears 7 8 on the rear end of the final conveyer, and thus serve to releasably connect the car and loading-machine together. When it is desired to disconnect a car, the catches may be swung on their pivots until the arms no longer project into the opening.

In Fig. 4 a modified connection is illustrated. Instead of mounting catches on the car the ears upon the rear end of the final conveyer are made movable. A fragment of one side 27 of the final conveyer is shown. It is provided with a hole 28, through which an ear 29 extends. The ear is mounted upon aspring 30, secured to the side of the final conveyer and provided with a handle 31, by which it may be manipulated. The opposite side is, of course, provided with a similar ear. These ears, engage directly with the sides of the opening in the rear wall of the car. Their front surface is inclined, so that in connecting a car to the loading-machine they operate automatically, the sides of the opening in the car pressing them in as the car and loadingmachine are brought together, and the spring 30 throwing them out when the car has moved up far enough to carry the rear wall beyond them. When it is desired to disconnect, the ears are manually pressed in by means of the handles.

What I claim is l. Amine-car comprising side and end walls, one of said walls having an opening therein adapted to receive a part of a loading-machine, and means on said wall normally projecting into said opening to engage said part to couple said car and loading-machine together.

2. A mine-car comprising side and end walls, one of said walls having an opening therein adapted to receive a part of a loading-machine, and catches to connect said car and loadingmachine adapted to be operated by the introduction of said part into said opening.

3. Amine-car comprising side and endwalls,

one of said walls having an opening therein adapted to receive a part of a loading-machine, and gravity -catches upon opposite sides of said opening having arms extending therein.

L. A mine-car comprising side and end walls, one of said walls having an opening therein adapted to receive a part of a loading-machine, and gravity-catches upon opposite sides of said opening having arms extending therein and adapted to be swung aside by the introduction of said part of a loading-machine.

5. A mine-car comprising side and end walls, one of said walls having an opening therein adapted to receive'a part of a loading-machine, and gravity-catches upon opposite sides of said opening having arms extending therein, said arms being pyramidal in shape.

6. A mine-car comprising side and end walls, one of said walls having an opening therein, gravity-catches upon opposite sides of said opening having arms extending therein, and a bearing-roller rotatably mounted adjacent to the lower side of said opening.

7. A mine-car comprising side and end walls, one of said walls having an opening therein, gravity-catches upon opposite sides of said opening having arms extending therein,brackets mounted adjacent to the lower side of said opening and a bearing-roller journaled in said brackets.
